A book in Takarajimasha's TJ Mook line that combines Disney character coloring pages with saving money. Each day has a set amount. You put the coins in a piggy bank, then color in that part of the page to record it.
When the whole book is colored, the Disney character pictures are complete and the savings add up to 700,000 yen. It comes with colored pencils in a case with a Mickey and Minnie design.
